There is nothing else that can cause this in a clean undamaged unmodified G11 or GM8 mount with tucked servos and sprung Gen II OPWs. -- Chip Louie Chief Daydreamer Imagination Hardware Astropheric

Sam, I appreciate your kind comments.? The telescope is Newtonian 12" truss F3.9 https://www.youtube.com/watch?v=cZzmiLg_Rys&t=6s ( https://www.youtube.com/watch?v=cZzmiLg_Rys&t=6s ) Camera is an ASI

” If your back off screw doesn't seem to be working it could be that the bottom cap screws are just a bit too snug to let the OPW move. If they are just a little bit too snug they lock the OPW into

Agree, Peter- really astonishing! Rivals Hubble images imho. I especially like the dynamic quality of the image, or percussion effect, as you describe. Can you share any other technical information

Mark glad to hear things improved haha yes, i love that sentiment ;)

Also, when you have good models for both sides, and you don't move the mount, you can either reset CWD and use Warm Start, or just power up and use Warm Restart.. Both use the model you made

Going to the west side, I told it to go to Mizar. It was not very close (not on the finder, but it was on the Telrad). I centered, clicked Menu>Align>Alignment. And declared victory for the modeling.

Hi Mark, Sounds like you're making progress! The thing about Gemini model is that it can take into account additional variables, like axis non-perpendicularity or even mirror flop, if you add a few

Very good, Mark,...that you got back to useability. There can be also good value to dig into why the pointing may be imperfect, if you now, having built a Model using your Gemini: Look at the model

We had a clear night tonight, with no wind or moon. So out I went again. After polar aligning with Polemaster (probably not necessary, since the tripod hadn’t moved, but good practice), I turned off

Peter that's a spectcular image, thanks for sharing!? 30 hours integration, a lot of work but it really paid off.? No better way to conclude a discussion than obtaining results like these.? Well

The manual <https://diffractionlimited.com/wp-content/uploads/2016/09/st-i_manual_1_1.pdf> says: GUIDE PORT: This is where you connect the supplied 6 conductor modular phone style cable to the

Hello all, I need to repair/replace the RA gearbox on my G11 with OPWB and Maxxon motors. Looking up instructions, I can see that this is relatively simple for standard worm/block with worm gear

I'd love to see the logs, but ASIAIR requires internet access since the only way to get at the logs is to email them. If you're imaging in the field using the internal ASIAIR wifi, you're out of luck.

The iconic bubble nebula is 7 light-years across and 7,100 light-years from Earth in the constellation Cassiopeia. I've tried to capture the percussion effect in this image, in the waves of radiating

If the issue was successful plate solving but the centering routine never quite made it after successive attempts, then yes this would be something to look at My understanding from the OP was that it

This link on the Facebook ASIAIR page explains the issues. Basically, change mount setting to Jnow. https://www.facebook.com/groups/ASIAIR/permalink/1864925700337311/

I had something similar with the original version. It turned out it was a difference between Jnow and J2000 settings between the mount and the ASI Air. Off the top of my head, both should be set to

I must be missing the story then? :) That doesn't really say anything other than the mount and asiair were in agreement to within 1 arcsecond of the slew and app. That is probably a pixel or two (not

Hi Brian, The image attached tells the story. ASIAIR's auto-centering fails to plate-solve and never centers the object in the FOV. Notice the coordinate mismatch. It's just 1 arc-second difference,
